Ebay Partner Network.............
Yeah, I do OK, though it's not really my focus, I just find info-type Adsense sites easier than product-based sites. But there is a bit of a negative vibe around EPN that dates back to when they introduced the new PPC-style program (they got ripped off really badly when they were in CJ, by cookie-stuffers and stuff, so they are really strict about that now). But actually, it's a pretty good program if you know how to promote it right. I create little "mini-authority" sites around products that sell really well on eBay (you HAVE to research how well they sell on eBay, or it won't translate into sales and good EPC - makes sense really). I use Wordbay to insert live auction listings into my posts and pages, but I really keep those low-key. Google DOESN'T like thin affiliate sites - remember what happened to BANS sites..? I just put two to four live listings in there, you don't really need any more.
The trick is really to then create a lot of long-tail type content around "sub-keywords". You want to end up with a lot of long-tail traffic and a lot of clicks, and if it's a good niche, you can get, say $0.30 EPC (though that's not all that easy to get for newbies), and then tons of clicks translate into good money. And CTR is not an issue like with Adsense

.
So yeah, I am surprised more people don't get back into EPN because it's another good revenue stream - 7-day cookie, money straight into Paypal about 3 weeks after month's end, and a lot of niches you can tap into that you just won't be able to monetise with Adsense ("vintage cassette players", that kind of thing!)
